Proton Conducting Copolymer Electrolytes Based on Vinyl Phosphonic Acid and 5‐(Methacrylamido)tetrazole

Abstract

Copolymer electrolytes based on 5‐(methacrylamido)tetrazole (MTet) and vinyl phosphonic acid (VPA) are prepared. The obtained copolymers are analyzed by FTIR, 1 H NMR, 13 C NMR, and 31 P NMR spectroscopy, thermogravimetric analysis (TGA), differantial scanning calorimetry (DSC), energy dispersive X‐ray spectrometry (EDS), elemental analysis (EA), cyclic voltammetry (CV), and impedance spectroscopy. The morphology of the copolymers is characterized by X‐ray diffraction (XRD), atomic force microscopy (AFM) and scanning electron microscopy (SEM). The highest proton conductivity is obtained as 0.01 S/cm at 150 °C and in anhydrous conditions. image
